Cisco Cisco IOS XR Software Release 3.2

Due to flash filesystem version changes being handled during upgrade, the LCs take longer to come up 
during upgrade from 3.0.1 to 3.2.2. 

Verify system stability through commands described in 

. If system 

issues are detected or the newly activated software must be backed out for any reason, follow the steps 
described in 

 to roll back the software configuration to a previous 

rollback point.

Commit the newly activated software:

RP/0/RP0/CPU0:router# admin
RP/0/RP0/CPU0:router(admin)# install commit

In 3.2.2, admin mode is required to run install commands. 

Restore/verify access to the boot flashes on RP and standby RP, as follows:

RP/0/RP0/CPU0:router# format bootflash: location RP_location

RP/0/RP0/CPU0:router# dir bootflash: location RP_location

RP/0/RP0/CPU0:router# format bootflash: location Standby_RP_location

RP/0/RP0/CPU0:router# dir bootflash: location Standby_RP_location

Now restore any user files from the harddisk back to the boot flashes.

RP/0/RP0/CPU0:router(admin)# copy harddisk:/source bootflash:/destination
